Here is the original item:
Despite her parents' disapproval,
(A) Tran
continues to date Charlie.
(B) A nice young
man (C)
whose only fault is not being born Vietnamese.
You wanted to do this:
Despite her parents' disapproval Tran continues
to date Charlie. A nice young man whose only fault is not being born Vietnamese.
Removing the comma after disapproval does not fix the fragment that occurs later in the item. Reconsider your choices.
